Indwangu ye-PTFE enezinga eliphezulu lokushisa (i-PTFE-coated fiberglass) inokumelana nokugoba okumpofu ngenxa yokuthi i-fiberglass substrate i-brittle ngokwemvelo. Izindwangu ezizacile (0.08mm) zisinda emakhulwini kuya ezinkulungwaneni zokugoqa; amamaki asindayo (>0.25mm) aqhekeka ngemva kwenqwaba. I-Satin weave idlula i-plain weave. Ukuze uthole ukugoba okuqhubekayo, cabangela ifilimu ye-PTFE eqinile noma indwangu esekwe ku-aramid esikhundleni.

Indwangu ye-PTFE yokushisa ephezulu (i-PTFE-coated fiberglass) isetshenziswa kakhulu ekuphrinteni kwendwangu nokudaya amabhande okuphrinta okudlulisa ukushisa (180-230°C), izembozo zetafula lokuphrinta isikrini, amabhande anezikhala okomisa, amabhande omshini wokuhlanganisa, nokugoqa kwamarola. Indawo yayo enganamathi ivimbela izinsalela zikayinki/zokunamathela, kunciphisa isikhathi sokuhlanza nokuthuthukisa ikhwalithi yendwangu. Amabhande angapheli angenamthungo anika amandla ukukhiqiza okuqhubekayo.

Indwangu ye-PTFE enezinga eliphezulu lokushisa (i-PTFE-coated fiberglass) iyisihlungi semidiya ye-premium yezimo ezimbi kakhulu: ukukhishwa kwegesi ye-flue (usimende, ukushiswa kwemfucuza, amabhayela amalahle afika ku-260°C), ukuhlunga uketshezi okugqwalayo (ama-acids, ama-alkali, uwoyela), ukuhlunga ukudla/kwemithi okuyinyumba, nezihlungi zegumbi lokuhlanza i-HEPA. Indawo enganamatheli ivimba uthuli futhi ivumela ukuhlanzwa kalula. Amabanga ane-Membrane-laminated athola ukukhishwa okuphansi kakhulu.

Indwangu ye-PTFE enezinga eliphezulu lokushisa igcina kahle kakhulu ukwahlukanisa kukagesi ukusuka ku- -180°C kuya ku-260°C: ukumelana nevolumu >10¹³ Ω·cm ku-200°C, i-dielectric ihlala iqinile kokuthi 2.0-2.1. Ngaphezulu kuka-260°C, i-PTFE iyathamba, ibole ngaphezu kuka-327°C, ilahlekelwa ukufakwa kwamagciwane unomphela. Ngaphansi kuka-0°C, ukwahlukanisa kuyathuthuka kodwa ukunamathela kuba nzima. Hlala ku-260°C ukuze uthole ukusebenza okuthembekile.

Indwangu ye-PTFE enezinga eliphezulu lokushisa (i-PTFE-coated fiberglass) ilungele amabhande okuthutha ukudla ngenxa yokumelana nokushisa kwayo okungu-260°C, -70°C ukuguquguquka okubandayo, indawo enganamatheli, kanye nokuthobela kwe-FDA. Izicelo ezibalulekile: ohhavini bebhikawozi (amabhisikidi, isinkwa, i-pizza), izinto zokuthutha ukudla okuthosiwe, izintambo zokupholisa uswidi, imihubhe eqandayo, izinto zokuvala ukushisa, nokugoqwa kwamarola. Yehlisa imfucuza nesikhathi sokuhlanza.

Ukuminyana kwe-warp ne-weft yendwangu ye-fiberglass inquma ukusebenza kwendwangu ye-PTFE yezinga eliphezulu lokushisa. Ukuminyana okuphezulu kukhulisa amandla okudonsa kanye nokushelela kwendawo kodwa kunciphisa amandla okudabuka (ijika le-U elihlanekezelwe), ukuguquguquka, kanye nokungena okunamathelayo. Ukuminyana okuphezulu kulinganisa ukungena, ukumelana nokukhala, ukuguquguquka, nokuqedwa kwendawo. Ukuminyana okuphansi kufanelana nokugoba okuguquguqukayo; high density for non-stick kanye ukwahlukanisa.

I-Calender – ukucindezela indwangu eboshwe nge-PTFE phakathi kwamarola esibuko ashisisayo ku-360-380°C – kushintsha ngokuphawulekayo ukumila kwendawo, ukukhulula izakhiwo, ukungaboli, nokusebenza komshini. Yehlisa ukuhwaqaza ukusuka ku-Ra 0.5-1.0 μm kuya ku-<0.05 μm, ivala amaphinifa, ithuthukise ukumelana nokugqoka, kodwa inciphisa amandla okudabula nokuguquguquka. Ibalulekile ekukhululeni ama-liner kanye nokufakwa kukagesi.

Indwangu ye-PTFE enezinga eliphezulu lokushisa eliphezulu nendwangu ye-silicone kokubili kusebenzisa indwangu ye-fiberglass njengesisekelo kodwa ihlukile ezintweni zokumboza (i-PTFE resin vs irabha ye-silicone). I-PTFE iphumelela kakhulu ekungabambeni, ukumelana nokugqoka, kanye nokumelana namakhemikhali kufika ku-260°C. Indwangu ye-Silicone inikeza ukuguquguquka okuphakeme, ukufakwa kukagesi, nokumelana nomlilo (kufika ku-230°C). Khetha ngokusekelwe kokubalulekile kwakho.

Indwangu ye-PTFE ephezulu yokushisa (i-PTFE membrane material) iyinketho ephambili yezakhiwo eziqinile. Izinzuzo eziyinhloko: iminyaka engu-30+ yokuphila kwangaphandle, indawo ezihlanzekile (amanzi emvula ageza ukungcola), ukudlulisa ukukhanya okuthambile (6-13%), isilinganiso somlilo Sekilasi A, namandla afana nensimbi angaphansi kuka-1.5 kg/m². Isetshenziswa ezinkundleni zemidlalo, ezikhumulweni zezindiza, namabhilidi ayisakhiwo sodumo emhlabeni jikelele.

Indwangu ye-PTFE enezinga lokushisa eliphezulu inikeza ukumelana kwamakhemikhali okukhethekile, imelana nama-acids aqinile, ama-alkali, izinyibilikisi eziphilayo, namagesi abolayo. Lesi sihloko sichaza ngezinto ezimelana nayo, imikhawulo (izinsimbi ze-alkali ezincibilikisiwe, ama-ejenti anamandla e-fluorinating), nezici ezibalulekile ezifana nezinga lokushisa, ukugxilisa ingqondo, nokucindezeleka komshini.
